FIRE-"PLUG.

SPECIFICATION forming part of Letters Patent No. 595,506, dated December14, 1897.

Application filed April 26, 1897.

To all whom it may concern..-

Be it known that I, EDGAR G. WILEY, a citizen of the United States,residing at Lynchburg, in the county of Campbell and State of Virginia,have invented a new and useful Improvement in Fire-Plugs, of which thefollowing is a full, clear, and exact description.

My invention is an improvement in fireplugs or hydrants; and it consistsin certain novel constructions and combinations of parts, as will behereinafter described, and pointed out in the claim.

In the drawings, Figure 1 is a vertical longitudinal section of myhydrant. Fig. 2 is a side view of the upper part thereof. Fig. 3 is adetail section of the plug-valve seat. Fig. 4 is a top plan view of saidseat, and Fig. 5 is anenlarged section of the lower end of the plug.Fig. 6 is an enlarged section on line 6 6 of Fig. l.

The plug is shown as consisting of the casing A and the stand-pipe B,the latter fitting within the casing and clamping the plug-valve seat 0in place. In connecting the stand-pipe and casing to secure thisclamping of the valve-seat O, I provide the casing internally near itsupper end with seats for the bolts D, which connect the stand-pipe andcasing, and provide for these bolts openings in the standpipe in linewith the interior of the casing, as best shown in Fig. 1, in order tosecure the clamping together of the casing and standpipe without anylateral projections to afford a surface against which the earth maypress as it swells in such manner as to lift the plug. I also seek toform the plug in such shape as to avoid any lifting thereof by theupswelling of the ground by tapering the casing A inward slightly from apoint slightly below its middle to its upper end, such taper being inpractice very slight and hardly perceptible to the eye.

In the specific construction shown of the connection between the casingand stand-pipe 1. form the casing near its upper end with the internalupper and lower flanges E and F, spaced apart and affording between thema seat for the heads 01 of the bolts D. The flange E is provided atintervals with slots 6, which permit the passage of the heads at of thebolts, which when inserted may be slipped beneath the flange E by apartial turning of Serial No. 633,950; (No model.)

the stand-pipe B, and the said bolts may be removed by reversing suchoperation, thus enabling the application and removal of the stand-pipewithout entirely removingthe nuts of any of the bolts D.

The stand-pipe B is provided on its outer side with a ring-likeprojection G, which has formed through it the openings 9 for the boltsD, thus forming a strong connection for such bolts D in such manner asto avoid any lateral projection beyond the side of the casing A.

The valve H, being the plug-valve, is fitted to the seat 0 and ispreferably double-faced, having its packing formed with the two faces hIt, so it may be reversed when worn or when one face for any otherreason is defective.

The casing A is provided with the wasteoutlet, and a suitablevent-outlet is provided leading from the stand-pipe into the casing.This vent-outlet is shown as formed through the valve-seat 0, controlledby a valve I, operating on a seat J, which controls the openings j,which lead from the interior of the stand-pipe and are formed in atubular extension J, which surrounds and projects upwardly from the seatJ for the valve I. This valve I is weighted at I and is provided at Iwith a portion which projects into position for engagement by the valveH when such valve is closed, so the closing of the valve H will open thevalve I to permit water within the stand pipe to pass out through theopening j and valve-seat J into the casing and thence out the opening j,as will be understood from Figs. 1 and 5.

As best shown in Figs. 3 and 4, the vent outlet is formed integral withthe valve-seat O, and in order to receive the tubular eXten- 9o sion Jand the valve I, I provide the standpipe B with a lateral pocket B, asshown in Figs. 1 and 5, such pocket furnishing on the stand-pipe anoffset corresponding to the off set formed at O on the valve-seat C,which 5 results from the provision of parts J J, as best shown in Fig.4:. This arrangement of the vent-outlet is certain in its operation,permits the draining of the stand-pipe down to a point but a shortdistance above the plug-valve, I00 and furnishes both the plug-valveseat and the vent-outlet-valve seat in the same part,

facilitating both the manufacture and applibolt-heads, the stand-pipehaving on its outer lo cation thereof, as will be understood from theside a ring-like projection provided with openin gs for the bolts, andthe bolts passed through drawings.

Having thus described my invention, what said openings and fitted toengage with the 5 I claim, and desire by Letters Patent, is seat of thecasing, substantially as described.

A plug comprising the casing having in- EDGAR O. XVILEY. ternally nearits upper end upper and lower Vitnesses: flanges forming a seat for thebolt, the upper D. II. HOWARD,
